    2. Debris flows carrying saturated solid materials in water flowing down slopes typically cause severe harm to the lives and properties in their path. Shut watching and early warning area unit imperative to avoid wasting lives and scale back harm. Current rubbish-flow-monitoring systems sometimes install device instrumentality on the riverbanks and mountain slopes to discover debris flows and track their knowledge. Sadly, most of this instrumentality indirectly collects knowledge solely from a distance. So far, there's no thanks to perceive what's happening within a rubbish flow and to gather its internal parameters, to not mention doing this in real time. To answer this challenge, this paper presents a unique multifunctional wireless device for watching rubbish flows. The core plan is to let these sensors drift with the rubbish flow, to gather flow info as they move on, and to wirelessly transmit the collected knowledge to base stations in real time. the look of such a device must address several difficult problems, as well as value, readying efforts, long standby, and quick reaction. This paper addresses these problems and reports our analysis results.
